TRus'sEn AxLE FOR WHEELEO VEHICLES.

SPECIFICATION forming part of Letters Patent No. 591,736, dated October 12, 1897.

Application filed May 2l, 1897. Serial No. 637,564. (No model.)

To all whom it may concern:

Beit known that I, JOHN STODDART BROWN, a citizen of the United States, residing at Galveston, in the county of Galveston and State' of Texas, have invented new and useful Improvements in Trussed Axles for l/Vheeled Vehicles, of which the following is a specification.

This invention relates to that class or type of axles for wheeled vehicles wherein a metal truss rod or bar running longitudinally under the axle-body has its end portions extended through the axle-skeins and secured by screwnuts which abut the outer ends of the skeins.

In the prior constructions it is essential to provide two independent screw-nuts at the outer end of each axle-skein, one designed to secure the end of the truss-rod and the other to retain the axle-box on the skein.

The chief object of my invention is to provide new and improved means whereby a single nut at the outer end of each axle-skein secures the extremity of the truss-rod and retains the axle-boxen the wheel of the axleskein.

To accomplish this object, my invention consists in the combination, with an axlebody, of an axle-skein mounted thereupon and having an internally-screw-threaded outer end, a truss-rod having one end arranged in the axle-skein, an axle-box rotatable on the skein, and a nut engaged with the truss-rod and the skein and retaining the axle-box on the latter.

The invention is illustrated by the accompanying drawings, in which'- Figure l is a sectional side elevation of an axle embodying my invention; and Fig. 2 is a longitudinal sectional view, on a larger scale, of one end portion of the axle for the purpose of more clearly illustrating the construction of the parts.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, wherein- The numeral l indicates the axle-body, composed, preferably,-Of wood, but which may be of any material suitable for the purpose. The end portions of the axle-body are provided with rigidly-attached axle-skeins 2, having collars 3 at or near their inner ends.

nal groove in the under side of the axle-body and having its end portions extended through the axle-skeins. The extremities of the trussrod 7 are provided with screw-threads 8, running in the same direction and of the same pitch as the internal screw-threads 4 of the axle-skeins. The screw-threaded extremities 8 of the truss-rod engage a screw-threaded socket formed through the center of the nut 6.

The nuts 6 screw upon the screw-threaded extremities 8 of the metal truss rod or bar at the same time that they screw into the outer ends of the axle-skeins in such manner that while the screw-nuts engage the truss-rod and the axle-skeins they serve to retain the rotatable axle-boxes 9 upon the axle-skeins. The axle-boxes 9 are designed to be secured in the wheel-hubs in any suitable manner. As here shown, a metallic washer l0 is arranged between the head of each nut and the outer extremities of an axle-skein and au axle-box. The washers IO are each of a diameter greater than the diameter of the bore of an axle-box, so that the washer will serve as an abutment to retain the axle-box upon the axle skein. Obviously, however, the Washers can be dispensed with and the heads of the nuts serve to retain the axle-boxes on the axle-skeins. By the means described I dispense with one of the nuts ordinarily employed at each end of the axle and render a single nut susceptible of securing one end of the truss-rod and retaining one of the axleboxes on an axle-skein.

The truss-rod braces the axle-body and ren` ders it strong, substantial, and durable, Vand the screw-nuts and internally-screW-threaded skeins provide novel, simple, efficient, and economical means for obtaining the results stated.

Having thus described, my invention, what I claim is- IOO 1. The combination with an axle-body, of an axle-skein mounted thereupon, a tru ss-rod having one end arranged in the axleskein, an axle-box rotatable on the skein, and a nut engaged with the truss-rod and the skein and serving to retain the axle-box on the latter., substantially as described.

2. The combination with an axle-body, of

3. The combination with an axle-body, `of an axle-skein mounted thereupon and having an internally-screwthreaded outer end, a truss-rod having one end arranged in the axle-skein, an axle-box rotatable onthe axleskein, and an externally-screW-threaded nut screwed into the axle-skein and having a vscrew-threaded socket engaged with the end of the rtruss-rod, substantially as described. In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
